+=== Description
+After creating a link:setup{ext-relative}[setup()] function, which initializes and sets the initial values, the `loop()` function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond. Use it to actively control the Arduino board.

-=== Description
-The `setup()` function is called when a sketch starts. Use it to initialize variables, pin modes, when you start using libraries, etc. The setup function will only run once, after each powerup or reset of the Arduino board.
